金华市区公园表层土壤铅污染分析及预防措施

Pb Pollution Analysis and Precaution Measure is Surface Soils of Urban Parks of Jinhua

对金华市区10个典型公园的表层土壤Pb含量做了调查分析,运用地积累指数法对公园表层土壤Pb污染进行了评价。结果表明,市区公园表层土壤Pb的平均含量为41.37 mg/kg,超半数公园为轻度污染至中等污染,即金华市区的公园表层土壤Pb含量污染并不是很严重。通过对土壤Pb含量的空间分布分析发现,金华市区公园土壤中Pb主要来源于交通和工业污染。

Pb concentrations in surface soils of 10 representative urban parks of Jinhua city were determined Geoaccumulation index was used to assess Pb pollution of the surface soils. The result showed that the average Pb content of soils was 41.37 nag/kg, more than half of the parks were light and medium heavily polluted. Lead contamination of Jinhua urban parks were not very severe. The spatial distribution of Pb concentrations showed Pb might come from traffic and industry.
